3 PC Battery-Powered Motion Light 2 Pack

Great little lights! Certainly good for the price. The installation options - magnet, or 3M adhesives - make them very flexible. I use these in an older home where my ceiling fans are on a single switch - I like leaving the fans on with lights off when not in the room, so these lights provide the necessary lighting when just passing through one of the dark rooms or when you need to enter and find the pull chain to turn on the main lights.I have one of these mounted to the ceiling fan housing - the fan blades do not activate the light's motion sensor. Another is used in an entry room which is normally dark - light works great for the short time needed to make the entry safe. As a special note, the light sensor can be neutralized so these lights can be used together to provide interior lighting for a gun safe if you don't have the option of an electrical outlet in your safe. Thankfully, a few other reviewers mentioned canceling the light sensors - one wrote about cutting wires, another wrote about using black tape to cover the internal sensor. I wouldn't cut any wires. I recommend using black, electrical tape to fully cover the small sensor. You will need to open the back, as if doing so to install the batteries. At this point, you will see three small screws; remove the screws to access the circuit board with the sensors. The motion sensor is the large dome in the center; off to the side of the dome, you will see a small clear, square component - this is the light sensor. You will need to cover it completely - I suggest two small pieces of the tape, applied to make a + over the sensor and sticking to the circuit board on all four sides of the sensor. Once the tape is secured, replace the cover without replacing the screws; install the batteries to test it. The light will come on when the third battery is installed. Allow the light to go out. Have the unit in a lighted area, then make a motion near the unit. If the light activates, you are good to go. If not, check to make sure you have covered the light sensor. Once it is verified to work in a lighted area, complete the replacement of the cover with the screws. Now you are ready to install the lights in your safe, or other cabinet. If you have a large safe with an electrical outlet, I recommend you purchase a Torchlight LED lighting system. They are available via Amazon and work fantastic!
